Samenvatting

This paper presents a reconfigurable receiver with frequency-independent blocker suppression in a 40nm CMOS technology. In linear mode, the receiver achieves an in-band B1dBof -25.7 dBm at 1MHz offset with 34 dB gain setting. In nonlinear mode, blocker suppression is achieved by dynamically adapting a nonlinear transfer function according to the blocker amplitude. In the presence of a 0 to 9.6 dBm blocker, the receiver provides more than 38 dB of frequency-independent suppression, while consuming 8.7-15.7 mW in the RF stage. The maximum attainable blocker level exceeds PDC-5dB. The measured in-band B1dBis from -2.8 to 8 dBm at 1MHz offset for different settings. The measured blocker NF is 15.47 dB with a 1.95 dBm blocker.
